Default Cable clutch conversion???

I had to do some fighting with my clutch this past holiday and my friend (who is an avid mustang fan) asked me why I didn't just go to a cable clutch. I had never heard of that, but he tells me most late mustangs all use cables! I can't find anything on the forum about it, and my searches on google don't turn up anything either. Anyone done this? Has the hydraulic issues with the master and slave been fixed yet?

In case anyone is curious as to what is happening here you go:

My clutch disengages way at the bottom of the clutch as first, then it will move to the middle of the pedal (where it feels good), then later back to the bottom of the pedal. I have tried to bleed it the old fashioned way and it change at all. Thoughts?

"I have tried to bleed it the old fashioned way"

From memory have to unbolt slave from bellhousing so get air to top when bleeding.

I got lucky and with a shorty wrench could turn loosen and tighten it in place. I also had a lift at my disposal and a second person. Definitely helps. The bleed nut was already at the top. I'm pretty sure the slave is dying. I had the master replace about six months ago, and the clutch has the same issue.

Cables clutches=bad. A lot of Mustang guys have problems with adjusters, quadrants, cable breakage, poor feel, lack of adjustment. My friend's Mustang has broken 4 cables in a row. And I can't imagine having to adjust it.

I'll take my hydraulic clutch any day of the week.

No one has done it yet.

I think it's a great idea, and is a 100% improvement over our crappy hydraulic systems. I have it all designed in my head how to do it, but I don't have the machining equipment to make it happen.

It would be great, and by messing with quadrant size you could change the force on the pedal. That would allow us to use a stronger pressure plate and still maintain relatively low pedal pressure. That would open up a whole new world of performance clutches for us.

Cable breakage could potentially be a problem, but I really think a well thought out system with the appropriate sized cable would work great.

Anyway, I think it's a great idea. Pioneer it man, you'll sell 20-30 of them probably.

Check out ZFDoc's article on slaves with the main diaphram installed backwards. Even a new slave can still be a problem unless it's been flipped.

Done that. That is what started my wondering. I am in contact with bruce from monderndriveline.com and he is looking to see what he can find from his sources. Let's see what he finds.
